What term describes starting a vehicle using an external power source?

• A. Jump-starting
• B. Parallel Start
• C. External Start
• D. Boosted Start

Answer: (A)

Starting a vehicle with an external power source is called a jump-start. The battery normally provides the heavy current needed to turn the engine over, so when it’s dead or weak you bring in power from another source—like another vehicle or a portable jump pack—to supply that current and get the engine running. Once the engine starts, the alternator takes over and recharges the battery, making the external connection temporary. Other phrases like “Parallel Start,” “External Start,” or “Boosted Start” aren’t the standard terms used to describe this common procedure, whereas jump-start is the widely accepted, recognized term.
